> AI Engineer | Energy Industry | Greater Houston_

AI Engineer with 5 years of engineering and 3 years building production AI/ML systems. I architect agentic RAG systems, predictive ML pipelines, and compliance automation that run in enterprise environments.

class AIEngineer:
    def __init__(self):
        self.focus = [
            "Agentic RAG & Multi-Agent Orchestration",
            "Predictive Maintenance & Anomaly Detection",
            "MLOps & Production ML Systems"
        ]

    def deploy(self, model) -> Production:
        return model.notebook_to_production()

Ventures

Production RAG system with vector search and traceable citations. Retrieves precise answers from uploaded PDFs with [1] [2] source references pointing to exact documents and pages.

Next.js 16 • React 19 • TypeScript • Supabase pgvector • Voyage AI • Groq • Vercel

Production MLOps platform processing 50k+ sensor readings through Bronze/Silver/Gold medallion architecture. PySpark ETL pipelines feed real-time fleet health dashboards with automated drift detection and retraining triggers.

PySpark • Delta Lake • PostgreSQL • Streamlit • Plotly • Docker • Terraform
